MF 840 Vented Loop - 1-1/2"
Installing one of our vented loops will ensure that fluids will not siphon from tank to tank. Vented loops are commonly used in the marine toilet system and engine cooling system. The simple valve system incorporated in the top of the loop allows air to enter the line when not in use, yet effectively seals as water or other fluid passes through. Molded in Marelon, neither vent nor loop will corrode. The duckbill one way valve is designed to seal properly if particulate matter is present in fluids.
Specifications:
Barb Size: 1-1/2" (38.1mm)
Height: 5-1/4" (133.35mm)
Width: 7-3/4" (196.85mm)

The Trident Marin Extra Flex Corrugated Wet Exhaust hose works great. I had to replace the old hose coming from the generator muffler to the exhaust pipe going out the hull. The hose needed to be curved and the flex was perfect. Delivery was fast with no issues. Thank you
